JAMES V. BURKE, OF CHICAGO, ILLINOIS.

FlLTERlNG CAN AN'D RECEPTACL E.

SPECIFICATION forming part of Letters Patent No. 426,911, dated April29, 1890.

Application filed October 1, 1888. Serial No. 286,815, (No model.)

To all whom it may concern:

Be it known that I, JAMES V. BURKE, a citizen of the United States, anda resident of Chicago, in the county of Cook and State of Illinois, haveinvented certain new and useful Improvements in Filtering Cans andReceptacles, of which the following is a full and complete description.

The-purpose of the present invention is to provide a simple, cheap, anddurable filtering-receptacle, more especially adapted to receive wasteor impure oil from machinerybearings, &c., and remove therefrom themechanical impurities-such as particles of metallic grit, filings, anddirt of any kind leaving the oil in a pure and filtered condition in thebottom reservoir or receptacle, to be drawn off for use as required. Iattain such purpose by the construction and arrangement of partsillustrated in the accompanying .drawings, which represent a sectionalelevation of an apparatus constructed in accordance with my presentinvention.

As represented in the drawings, my improved apparatus consists of a mainlower tank-section or reservoir X, for holding the filtered oil, asuperimposed tank-section A, for receiving the unfiltered or waste oil,and a filter arranged within the tank A, and consisting of a body ofcotton-waste D or other like porous material inclosed between theperforated top and bottom grids B C, the bottom grid constituting adetachable bottom for the chamber A, the upper perforated grid, thatconfines the filtering material D in place, being also removable andresting on brackets B, as shown. WVith this construction the differentfilter parts are readily removable by handles 12 in a disconnectedcondition, so as to admit of easy cleaning of the different parts. Acounterpart grid B O is also provided in the lower tank-section X, andthe several grids are preferably formed with a flaring imperforatemargin and a central sieve portion 0, as shown.

The main purpose of the upper grid in the tank-section A is to retainupon the surface thereof iron filings, turnings, and grit when the sameare contained in the oil to be fil tered, and hence when such oil isfree from large particles of dirt or other matter said grid may beomitted, if desired, in the use of my invention.

E is the portion of the lower tank-section above its perforate grid B C.

The tank-sections X and vided with the usual handles 00 and a", and thetank-section X will be provided with the usual glass gage F, forindicating the height of oil within the same.

The present invention consists more especially in the construction ofparts whereby the sections X and A are detachably connected together andthe filter supported in position.

In my improved construction the lower edge of the wall of thetank-section A is bent or formed with an outturned annular flattenedbead or flange a, to fit over the top edge or rim of the tank X and forma support for the tank A, a downwardly-extending flange or rim a,adapted to fit within the opentopped rim or margin of the maintank-section X, to prevent leakage at the joint between thetank-sections, as well as lateral displacement, or. the too easydetachment of the two tank-sections X and A, and an inwardly-extendingannular flange a, to form an annular ledge within the chamber A forsupporting the lower perforate grid of the filter, as shown. Thesedifferent flanges a a a are formed integral with the sides of the tankA.

a is a stiffening-flange that may be used where extra strength of partsis required.

In use the tank-sections X and A may be suitably incased in wood, and itis not essential that the porous filling-body D shall completely fillthat portion of the tank A between the upper and lower perforate gridsof the same; neither is it necessary that the sieve portion 0 of thegrids B be of the same mesh or degree of fineness.

Having thus fully described my invention, what I claim as new, anddesire to secure by Letters Patent, is

A filtering can or receptacle comprising an upper and lower tank-sectiondetachably connected together, the upper section A being A will beproformed with an outturned flange a to rest sides of the tank-sectionA, in combination 011 the top rim of the tank-section X, a downwith afiltering-body confined between perfowardly-extending flange a, fittingwithin the rate grids B, essentially as herein described. to

rim of said section, and an inwardly-extend J AMES V. BURKE. 5 ingannular flange a forming a support for \Vitnesses: V
